Application filed April 26, 1911. Serial No. 623,430.

To all whom it may concern:

Be it known that I, LEVI CRAIG, a citizen of the United States, residing at Corinth, in the county of Grant and State of Kentucky, have invented certain new and useful Improvements in Removable Window Stop- Strips, of which the following is a specification.

- This invention relates to improvements in window frames and pertains to that class of frames wherein the sashes are adapted to be removed inwardly in order to facilitate the operation of cleansing the glass, or for other purposes which will be apparent, eliminating thereby much labor and risk of life during said operation.

An object of the invention is to provide efficient means for the removal of the sashes in combination with novel means for retaining the parting strips in place when the sashes are in their normal position in the frame.

With the above and other objects in view, this invention consists in the combination, construction, and arrangement of parts, all as hereinafter more fully described, claimed, and illustrated in the accompanying drawings, wherein Figure 1 is a view of a window frame or casing showing the application of the invention thereto; Fig. 2 is a vertical section of the frame showing the manner of removing the window sashes; Fig. 3 is a section taken on the line 3-3 of Fig. 2; Fig. 4 is a view partly in section showing the means for securing together the contiguous ends of the inner stop strips; Fig. 5 is a view of the frame broken away and partly in section showing means for securing the removable section of the parting strip; Fig. 6 is a view of the face plate; Fig. 7 is a view on the line 77 of Fig. 1; and Fig. 8 is a side view of the removable section of the parting strip, partly broken away and showing the hole for locking the same in position.

Throughout the following detail description and on the several figures of the drawings, similar parts are referred to by like reference characters.

Referring to the drawings 1 designates a window frame of conventional structure having the sashes 2 and 8 therein. The sashes 2 and 3 are positioned between the outer stop strip 4, the parting strip 5 and the inner stop strip 6, being slidable therebetween in the usual manner and having the cords and weights attached thereto, as customary in ordinary window sashes. The parting strip 5 is placed in a groove in the casing of the frame and consists of the stationary upper section and movable lower section, the latter being retained in position by means more fully hereinafter described. The inner stop strip 6 is likewise provided with a stationary upper section and a movable lower section, the latter being pivotally mounted on the inside of the frame 1, as by a pintle 7 The contiguous ends of the inner stop strip 6 are beveled and fastened in their normal position by means of the slide bolt or latch 8 of any ordinary construction.

As clearly shown in Fig. 5 of the drawings, the pintle 7 comprises a square shoulder portion passing through the lower end of the movable section of the inner stop strip 6 and has at its inner extremity a cam 9, the latter extending into a recess 10 in the casmg 1.

As most clearly seen in Fig. 3, there is provided a pin 11 located in the recess 10 in the frame, which pin is bent laterally at one end so as to engage over the cam 9 on the inner extremity of the pintle 7. The pin 11 extends inwardly and passes through the hole 12 in the lower end of the parting strip 5, thereby holding the lower portion of said strip from displacement while its upper end 1s held in position in the groove in the casing by means of the lower port-ion of the upper sash which is beveled oppositely to the upper portion of the lower sash in a manner which is common in the art. The pin 11 also passes through a spiral spring 13 normally tending to hold said pin in position in which its extremity passes through the parting strip 5. To prevent accidental displacement of the pintle 7 there is provided a face plate 1.4 through which the cam 9 is first inserted and, in positioning the face plate on the frame, the lower end of the plate is inserted in a groove 15 in the sill 16 of the frame 1. The upper end of the plate let is then secured to the casing by means of a screw 17.

In the operation of removing the sashes from the frame 1, it is first necessary to raise the slide bolt 8, thus permitting the lower section of the inner stop strips to be pulled inwardly by reason of the pintle 7 into a horizontal position, as shown in Fig. 2. The lower sash may then be displaced and allowed to rest upon the lowered inner stop strips. In lowering the said stop strips, the

cam 9 simultaneously with the movement pulls the pin 11 inwardly from engagement with the lower sections of the parting strips 5 and the sections are then removable. This permits the upper sash to be removed in like manner to the lower and the operator may then cleanse the outside of the window glass. The upper sash is then replaced and the lower movable section of the parting strip is placed in proper position and finally the lower sash in its normal position. The lower sections of the inner stop strips are then raised and locked into position by means of the slide bolts 8 and it will be apparent that, simultaneously with the upward movement of the said stop strips, the pin 11 engages in the lower sections of the parting strip by virtue of the tension of the spring 13.

Having thus fully described my invention, what is claimed as new is 1. In a window frame, sashes slidable in said frame, inner and outer stop strips, the former having movable sections, parting strips between the-sashes having removable sections, means for retaining the inner stop strips in their normal position, pintles secured to the lower ends of the movable inner stop strips and mounted in the sides of the frame, cams on the inner extremities of the pintles, and pins normally holding the parting strips in position and adapted to be engaged by the cams aforesaid to disengage the pins from the parting strips simultaneously with the lowering movement of the inner stop strips.

2. In a window frame, sashes slidable in said frame, inner and outer stop strips, the former having movable sections, parting strips between the sashes having removable sections, means for retaining the inner stop strips in their normal position, pintles secured to the lower ends of the movable inner stop strips and mounted in the sides of the frame, cams on the inner extremities of the pintles, and pins normally holding the parting strips in position and adapted to be engaged by the cams aforesaid to disengage the pins from the parting strips simultaneously with the lowering movement of the inner stop strips, and springs normally tending to hold the said pins in engagement with the parting strips.

3. In a window frame, sashes slidable in said frame, inner and outer stop strips, the former having movable sections, parting strips between the sashes comprising removable sections having openings in the lower extremities thereof and adapted to engage with one of the said sashes at their upper ends, pintles secured to the lower ends of the movable inner stop strips and mounted in the sides of the frame, cams on the inner extremities of the pintles, pins adapted to pass through the openings in the parting strips and to be engaged by the cams aforesaid to withdraw the said pins from the parting strip when the inner stop strips are lowered, and springs mounted on the said pins to normally hold the pins in the openings in the said parting strips.

In testimony whereof I aiiix my signature in presence of two witnesses.

LEVI CRAIG.
